FIELD OF THE INVENTION
The present invention relates to a hinged connector door assembly.
SUMMARY OF THE INVENTION
There is provided a connector door assembly for attachment to a connector housing, the connector housing comprising a rearward end configured for receiving a cable end terminated by a cable termination assembly and defining an opening. The assembly comprises a pair of opposed elongate doors each, a pair of parallel hinges arranged for pivotally connecting an outer edge of a respective one of the doors to the connector housing on opposite sides of the opening. A pair of supports each comprising a cable gripping surface, one of each of the supports mounted to a respective door, and a locking mechanism. When in a closed positon inner edges of the doors define a cable receiving opening there between, the elongate fingers of both of the doors together define a cable jacket receiving region there between.

DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS
Referring now to FIG. 1A, a hinged connector door assembly, generally referred to using the reference numeral 10, will now be described. The door assembly 10 comprises a pair of illustratively identical elongate opposed door members 12, 14 which work together to close the rear end of a connector housing 16 (such as a plug, as shown, jack/receptacle, or coupler not shown) about a cable 18. The cable 16 is typically comprised of a plurality of twisted pairs of conductors 20 which is terminated by a cable termination assembly and received within the rearward facing opening of the connector housing 16.
Referring now to FIG. 1B, the doors 12, 14 are each hingedly/pivotally mounted about each of a respective pair of parallel axes A-A, B-B by a hinge. In this regard, the hinge comprises opposed pairs of aligned pins 22, 24 which engage with aligned apertures 26, 28 formed in the opposed upper ends 30, 32 and lower ends 34, 36 of each of the doors 12, 14. The door 12, 14 may be opened to receive illustratively a suitably prepared cable termination assembly 38 into the rearward end 40 of the connector 16. Each door comprises an outer casing 42, manufactured from a rigid material such as diecast metal or plastic, a flexible cable gripping surface 44 and a locking plate 46. On closing of the assembly, the flexible cable gripping surfaces 44 flexibly grip the jacket 48 of the cable 18 there between for example for providing strain relief and increased mechanical strength.
Referring now to FIGS. 2A and 2B, each of the gripping surfaces 44 illustratively is comprised of a pair of fingers 50 which are formed such that when assembled and the doors 12, 14 closed, the opposed pairs of fingers define a cable receiving region 52 there between. Illustratively the flexible cable gripping surfaces 44 and locking plate 46 are interconnected by a mounting plate 54 and clip 56, all manufactured from the same piece of material, for example a resilient flexible conductive material such as nickel plated steel or the like.
Still referring to FIGS. 2A and 2B, during assembly the clip 56 is mated with an interlocking surface 58 on the respective door 12, 14. Additional bosses 60, 62, 63 moulded on the inside of each door 12, 14 provide additional support for the gripping surfaces 44 and the locking plate 46 thereby securing each assembly to their respective door 12, 14 in a friction fit. Each locking plate 46 further comprises a hooked end 64 and a release tab 66. When the doors 12, 14 are in a closed position, each hooked end 64 releasably engages a corresponding locking boss 68 moulded or otherwise formed into the inside of each door 12, 14. Simultaneously a lip 70 towards an end of each door 12, 14 is engaged in a groove 72 in the opposing door 12, 14.
Referring back to FIG. 1A in addition to FIG. 2A, the hooked end 64 of each locking plate 46 can be disengaged from its respective boss 68 by moving the opposed release tabs 66 towards one another, thereby releasing the doors 12, 14 and allowing them to eventually be pivoted about their respective axis A-A, B-B. Still referring to FIG. 1A, of note is that in an illustrative embodiment where a handle 74 is provided in order to release a front end 76 of a plug type connector 16 from a receptacle (not shown), in order to allow easy access to the upper release tab 66′, the handle 74 is staggered to one side of the connector 16.
Referring now to FIGS. 3A and 3B, the ends 78, 80 of each side 82, 84 of the connector 16 are profiled with chamfered surfaces 86, 88 and such that they project into the pathway of their respective door 12, 14 as the door is closed. As each door is closed, the tips 90, 92 of each of the chamfered surfaces 86, 88 engage the edges 94, 96 of their adjacent mounting plate 56. This, for example, improves contact between a metal connector housing 16, if used, and the mounting plate 56. In this manner continuous contact between a cable ground (not shown) such as a drain wire, foil or metal jacket or the like and the connector housing 16 can be established. Additionally, the interaction between each tip 90, 92 of the chamfered surfaces 86, 88 and their adjacent mounting plate 56 when closed can be used to bias the doors 12, 14, and such that when the release tabs 66 are actuated, the doors 12, 14 are biased into an open position.
Referring now to FIGS. 4A and 4B, in a first alternative embodiment, each of the doors 12, 14 comprises an integrated pair of mating locking tabs 98, 100 which mate like tabs on the opposing door thereby securing the doors 12, 14 in a locked position. Additionally, the flexible cable gripping surfaces are provided by a plurality of flexible plates 102, manufactured from metal or the like, which when the doors 12, 14 closed are arranged snugly about the cable, gripping the jacket (both not shown). Each of the plates 102 are mounted to a support 104 which comprises a mounting tab 106 which illustratively is moulded into a respective one of the doors 12, 14.
Referring now to FIGS. 5A and 5B, a second alternative embodiment of the door 12 is illustrated. Of note is only one door 12 is shown. The second door (14 in FIG. 1A) is the same, merely rotated 180 degrees about its length for mounting on the rearward end of the connector 16. In the second illustrative embodiment the flexible cable gripping surfaces are again provided by a plurality of small plates 108 mounted on a support 110, both manufactured from metal or the like, which when the doors 12, 14 are closed, are arranged snugly about the cable, gripping the jacket (again, both not shown). The support 110 in turn comprises a locking tab 112 and a clip portion 114 for mounting the support 110 about a mounting surface 116 moulded into the door 12. As will now be understood by a person of ordinary skill in the art, in operation the locking tab 112 comprises a hook 118 which engages a locking boss 120 moulded or otherwise formed in the opposing door.
Although the present invention has been described hereinabove by way of specific embodiments thereof, it can be modified, without departing from the spirit and nature of the subject invention as defined in the appended claims.
